No network signal after restart

Hi

My galaxy a72 doesn't have any signal.I had a problem with unresponsive screen lately and I opened the phone to clean and check after getting advice from here.Today while at was ar uni the same problem occurred I restarted the phone just to get by until coming home to change the flex cable(I ordered aa spare one) and since then I have no network connection. Wifi works fine.I tried everything. Can the flex cable cause this problem?

Thanks in advance.

PS I checked my sim on my brother's phone and vise versa. My on my phone I stilldidn't have any signal.

@juangeas I can't seem to find where you asked about this before and what advice you got for that. Let us know which flex cable you are referring to. Also, let us know if our phone recognizes that there is a SIM card.

Time to open it up and check your coax cables. Make sure they are properly seated etc. Depending on what Flex this is, if you have a replacement, now is a good time to install it.If you need to to a deep dive, use Samsung's flowchart for that.
